Due to tests not actually verifying the exit code of rlocation calls, a few special cases were not handled correctly. In particular, absolute paths still went through regular rlocation lookup and could fail there even after the absolute path had been printed to stdout. Also adds a missing newline in the (very rare) case that a manifest entry is found, but doesn't point to an existing file (e.g. if it is an unresolved symlink), and `rlocation` is not used with command substitution, but some other mechanism that doesn't strip trailing newlines. The tests now assert the expected exit code (== 0 or != 0). Fixes bazelbuild#16933
